The Bosch 12V Max Chameleon Drill/Driver features the FlexiClick® 5-In-1 Attachment System and is designed for professionals who want a high-quality tool that redefines their limits to get the tough jobs done. At only 1.8 Lbs. (tool only, not including battery) and 265 In.-Lbs. of torque, this robust drill/driver delivers the performance you expect in the size you want. It has two speed settings, for quick jobs and precision work. It starts with a magnetic bit holder for basic driving. The four attachments – a locking bit holder, a keyless chuck, an offset angle and a right angle– each attach to the tool securely and easily with the One-Click interface. The right angle attachment is for tight spaces, and it works with all three other adapters. The offset angle attachment delivers precise screwdriving close to edges. Both of these attachments rotate to 16 positions without removing them. The locking bit holder attachment locks hex bits for high-torque drilling, while the keyless chuck provides standard drilling.
